Hi robert,
My composite viewer is set as :
m_rpCompoViewer = new osgViewer::CompositeViewer;
m_rpCompoViewer->setThreadingModel(osgViewer::Viewer::SingleThreaded);
I've found a osg message "[osg-users] Adding Views to a Running
CompositeViewer" wich talks about the same problem as I have.
I've juste added the code below after calling :
m_rpCompoViewer->addView(rpView.get());
osgViewer::CompositeViewer::Windows windows;
m_rpCompoViewer->getWindows(windows);
// clear out all the previously assigned operations
for(osgViewer::CompositeViewer::Windows::iterator citr =
windows.begin();citr != windows.end();++citr)
{
if(!((*citr)->isRealizedImplementation()))
{
(*citr)->realizeImplementation();
}
}
and everything works fine.
